We want to divide 30436508 by 398.

On to step 1:
When dividing 3 by 398, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 398

On to step 2:
30 divided by 398 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 398

On to step 3:
398 goes into 304 0 times with a remainder of 304.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 304 to get 304.
Include the next digit (3) from the dividend after 304, then repeat: 3043 / 398

Moving on to step 4:
If we divide 3043 by 398, we get 7 and a remainder of 257.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 2786 from 3043 to get 257.
Include the next digit (6) from the dividend after 257, then repeat: 2576 / 398

Going ahead to step 5:
When dividing 2576 by 398, we get 6 with a remainder of 188.
Write down 6 as next digit of the result. 
Result so far: 76.0
Deduct 2388 from 2576 and we're left with 188.
Append the next digit (5) from the dividend to 188 and continue with: 1885 / 398

Going ahead to step 6:
398 goes into 1885 4 times with a remainder of 293.
Put 4 as the next digit of the answer. 
Result so far: 764.0
Deduct 1592 from 1885 and we're left with 293.
Grab the next digit (0) from the dividend, add it to 293, then carry on: 2930 / 398

Going ahead to step 7:
The number 398 fits into 2930 7 times, leaving a remainder of 144.
Put 7 as the next digit of the answer. 
Result so far: 7647.0
Subtracting 2786 from 2930 leaves us with 144.
Take the next digit (8) from the dividend and append it to 144, then repeat: 1448 / 398

Moving on to step 8:
If we divide 1448 by 398, we get 3 and a remainder of 254.
Write down 3 as next digit of the result. 
Result so far: 76473.0
Subtracting 1194 from 1448 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 9:
2540 divided by 398 is 6 with a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 76473.6
Deduct 2388 from 2540 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 10:
When dividing 1520 by 398, we get 3 with a remainder of 326.
Write down 3 as next digit of the result. 
Result so far: 76473.63
Subtracting 1194 from 1520 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Moving on to step 11:
The number 398 fits into 3260 8 times, leaving a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 76473.638
Subtracting 3184 from 3260 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
398 goes into 760 1 times with a remainder of 362.
The next digit of our result is 1. 
Result so far: 76473.6381
Subtracting 398 from 760 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 13:
3620 divided by 398 is 9 with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 76473.63819
Subtract 3582 from 3620 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
The number 398 fits into 380 0 times, leaving a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 76473.63819
Subtract 0 from 380 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 15:
398 goes into 3800 9 times with a remainder of 218.
Record the quotient 9 as the next digit in the result. 
Result so far: 76473.6381909
If we take 3582 away from 3800, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 16:
398 can be fit into 2180 5 times, resulting in a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 76473.63819095
Deduct 1990 from 2180 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

In conclusion, the division gives 76473.63819095 with a balance of 1.9e-07.
